PubNub is a great tool for developers looking for an easy to use, real-time messaging service. PubNub's Publish/Subscribe APIs are some of the easiest to use in the industry, and their speed and reliability of service are unparrell. While many companies out there offer a wide range of pubsub and message queuing services, I've personally found that PubNub is the easiest to setup and get started with. When I was an indie game developer, I used PubNub as the realtime chat component in my application, and it also powered realtime drawing between players. The cost compared to spinning up my own servers globally was much cheaper, and I was happy that I decided to go with PubNub. While you could build it yourself, why when PubNub makes it so easy to get something up and running. Spend less time coding and more time marketing, that's always been my philosophy. PubNub Unity

I recently used PubNub to implement a realtime leaderboard into my Unity game. It was easy and straight forward to get up and running. I choose Pubnub because they had a Unity SDK and an example project which showed me how to use it. I downloaded the example project and tweaked it to fit my game.

In their documentation I found good information about what I needed to know. Also, their support is very helpful when you have questions.

JetBrains Rider massively improves production speed and value. It's hard to find a tool/IDE that is so well designed like Rider (especially for Unity).

The folks at ReSharper do an awesome job with resharper-unity plugin. They even have a more in depth explanation of common issues in Unity than Unity itself.
